Compared with EPS foam, the cardboard can be degraded and recycled, which can reduce environmental pollution.

[0003] However, the existing packaging structure only uses the box shell and buffer liner of honeycomb cardboard to protect the product, and the honeycomb cardboard has the defect of low compressive strength, especially the buffer supporting force for large-weight and large-volume products is insufficient. Summary of the Invention

The second cover assembly includes a second cover shell, two second cardboard boards, two sets of second strengthening components, and two second end covers. The first cover shell and the second cover shell are respectively arranged in a U shape. The two first end covers respectively cover the two first openings oppositely arranged on the first cover shell, and the two second end covers respectively cover the two second openings oppositely arranged on the second cover shell. Moreover, an accommodation cavity for placing products is formed among the two first end covers, the first cover shell, the two second end covers, and the second cover shell. One first cardboard board covers the corner of the free end face and the outer side face of one of the two first side walls oppositely arranged on the first cover shell. One second cardboard board covers the corner of the free end face and the outer side face of one of the two second side walls oppositely arranged on the second cover shell. And one second cardboard board is in contact with one first cardboard board to form the accommodation cavity. One set of first strengthening components is adapted to one first side wall. Each set of first strengthening components includes a first strengthening rod and a third cardboard board. A first groove is formed on the outer side face of the first side wall. The first strengthening rod is located in the first groove. The third cardboard board correspondingly covers the corner of the outer side face of the first side wall and the outer side face of the first connection wall of the first cover shell. And one set of second strengthening components is adapted to one second side wall. Each set of second strengthening components includes a second strengthening rod and a fourth cardboard board. A second groove is formed on the outer side face of the second side wall. The second strengthening rod is located in the second groove. The fourth cardboard board correspondingly covers the corner of the outer side face of the second side wall and the outer side face of the second connection wall of the second cover shell. The first cover shell and the second cover shell are both made of honeycomb cardboard. The first end covers and the second end covers are made of fiberboard or wood board.

While further improving the cushioning performance, they have good supporting strength, thereby enhancing the structural compressive strength at both ends of the first cover shell and both ends of the second cover shell. In addition, on the outer sides of the two first side walls of the first cover shell of the present utility model arranged oppositely, first grooves are provided, and first reinforcing rods made of hollow paper tubes are embedded in the first grooves, thereby improving the structural compressive strength of the two first side walls of the first cover shell arranged oppositely. And on the outer sides of the two second side walls of the second cover shell of the present utility model arranged oppositely, second grooves are provided, and second reinforcing rods made of hollow paper tubes are embedded in the second grooves, thereby improving the structural compressive strength of the two second side walls of the second cover shell arranged oppositely. In addition, the first cardboard covers the free end face and the corner of the outer side of one of the two first side walls of the first cover shell arranged oppositely for corner protection to increase the structural strength at the corner. The second cardboard covers the free end face and the corner of the outer side of one of the two second side walls of the second cover shell arranged oppositely for corner protection to increase the structural strength at the corner. The third cardboard covers the outer side of the first side wall and the corner of the outer side of the first connecting wall of the first cover shell corresponding to the first reinforcing rod for corner protection to increase the structural strength at the corner. The fourth cardboard covers the outer side of the second side wall and the corner of the outer side of the second connecting wall of the second cover shell corresponding to the second reinforcing rod for corner protection to increase the structural strength at the corner. And the arrangement of the first cardboard, the second cardboard, the third cardboard, and the fourth cardboard can also disperse the pressure at the corner.

[0008] Compared with EPS foam (polystyrene foam), the packaging structure of the present utility model uses the first cover shell and the second cover shell made of honeycomb paperboard, the first end cover and the second end cover made of fiberboard or wood board, and the first reinforcing rod and the second reinforcing rod made of hollow paper tubes, all of which can be degraded and recycled, can reduce environmental pollution, and are green and environmentally friendly.

And one second cardboard board 125 is in contact with one first cardboard board 115 to form the receiving cavity. Moreover, one group of first strengthening components 112 is adapted to one first side wall 1111. Each group of first strengthening components 112 includes a first strengthening rod 1121 and a third cardboard board 1122. A first groove 11111 is formed on the outer side face of the first side wall 1111. The first strengthening rod 1121 is located in the first groove 11111. The third cardboard board 1122 correspondingly covers the corner of the outer side face of the first side wall 1111 and the outer side face of the first connecting wall 1112 of the first cover shell 111.
